Quite a few plants throughout North America have the common name of Blue-eyed grass. These different species of the Sisyrinchium genus have very similar identifying characteristics. This plant portrait features Sisyrinchium angustifolium.
The leaves are thin, linear and smooth — arising at the base of the plant.
Blue-eyed grass flowers have six bristle-tipped tepals which may look light blue through light purple in color. The center of the flower is bright yellow.
After the flower is fertilized, the seeds develop inside a spherical seed capsule.
